IMPROVEMENT lN SPINDLE-BOLSTERS 0F SPiNNING-MACHINES.

Specification forming part of Letters Patent No. 110,90, dated Decemberl5, 1S63.

To all whom it may concern:

Be it known that I, RICHARD FETHNEY, of the city of Manchester, in thecounty of Lancaster, Great Britain, machinist, have invented certainImprovements in Bolsters for Spindles Employed in Spinning, Vinding, andotherwise Manufacturing Fibrous Materials; and I do hereby declare thatthe following, taken in connection with the drawings which accompany andform part of this specification, is a'description of myinvention,suflicient to enable those skilled in the art to practice it.

This invention relates to an improved swivelbolster t0 be used inmachinery for preparing, spinning, doubling, and winding fibrous Part ofthe bolster is made of a globular or partly globular form, and fits are.- cess of a similar shape in the copping or spindle rail, there beinga pin or projection to prevent its revolving with the spindle. This pinor projection may either stand out of the bolster and fit into a slot ornotch in the rail or it may project from the rail and fit a slot orrecess in the bolster. on the upper or lower side ofthe rail or otherconvenient part a cap or other appliance to hold the bolster in itsplace, or the same effect is produced by entering a pin into a circularrecessin the bolster. This arrangement enables the bolster toaccommodate itself to any displacement or deviation of the copping ormovable rail, so that it can never bind the spindle, but will alwaysallow it to rotate freely, and thereby prevent much friction and effecta saving in oil, especially in those bolsters or spindle-rails thatslide up and down, as this form of bolster does not skim the oil off bypressing more on one side than the other. Any length of tube or bolstercan be used in order to give greater steadiness to the spindle when itruns at a high velocit-y.

rThese improvements will be clearly understood byreferring to thefigures and letters on the accompanying sheet of drawings.

Figure l is a cross-section drawn about half size of the copping orlifting rail of a rovingframe having my improved bolster. Fig. 2 is afull-sized section of one spindle and bolster, and Fig. 3 a full-sizedplan of the same; Fig. 4, a cross-section of the spindle-rail of athrostle or doubling frame with one of my improved bolsters; Fig. 5, alongitudinal sect-ion There is also fitted of the same; and Figs. 6, 7,8, .and 9 are vertical sections of modifications of my improved bolster.

In Figs. l, 2, 3, 4, and 5 a represents the spindle; b, the bolster; c,the cap which holds the bolster in its place; d, the copping or liftingrail in which the bolster is placed; e, a screw or pin for preventingthe revolution of the bolster, andf a screw for fixing the cap to therail. It will be seen from the construction of the bolster that if theposition of the copping-rail should be altered by the wearing of theslides, the sinking or displacement of its supports, or from any othercause,it can never bind the spindle, as the globular part of the bolsterwill accommodate itself to the change and still allow the spindle torotate freely, which would not be the case had it been tightly fixed inthe rail. The screw e enters a slot or recess in the globular part ofthebolster; but the point of the screw is not entered so far into the slotas to tighten the bolster, but merely to prevent its revolving with thespindle. This arrangement of bolster is very easily `fitted to the rail,however perfect the tit of the spindle, no reaming being required, as isthe case with the ordinary bolster. In some cases the bolsters are made,as at h, Fig. 1, with a collar for the bobbin-wheel to rest upon, inwhich case the cap c requires to be formed open in front. It will easilybe perceived that if a pin is fixed to theglobular part of the bolsterand arecess formed in the rail the revolution of the bolster may beeffectually prevented.

In Figs. 6, 7,'and 8 I represent vertical sections of myimprovedbolster, in which the cap is dispensed with. The spindle is shown at a,the bolster at b, and the copping orlifting rail at d. In thesearrangements the screw or pin d is caused to enter a circular recess inthe globular part of the bolster', and thereby prevent any vertical aswell as revolving movement. In some cases it may be desired to form thebolster partly globular, as shown at Fig. 9, in which the center partonly is curved, the other parts next the tube being cut away.

Letters Patent on this invention have been granted in Great Britain, andthe specification thereof enrolled May 5, 1862.

Having described the nature and particulars of my said invention, Idesire it to be understood that do not claim a globular bearing 2; Themeans, substantially as described,
